Vermiculite

Horticultural Vermiculite

Horticultural Vermiculite is an inorganic, inert, and sterile growing medium that provides excellent aeration, water-holding capacity, and plant insulation. Ultra-lightweight and free from disease, weeds, and insects, our vermiculite promotes healthy plant growth and is available in various grades to suit your needs.

Key Benefits of Vermiculite:

• Non-abrasive and slightly alkaline (can be neutralized with peat)
• High cation exchange (or buffering exchange) for optimal nutrient absorption
• Insulating properties protect plants from temperature fluctuations

Available Granule Sizes:

• Grade 1, Extra Fine = 0mm – 1mm
• Grade 2, Fine = 2mm – 4mm
• Grade 3, Medium = 3mm – 6mm
• Grade 4, Coarse = 5mm – 8mm

Perfect for Rapid Seed Raising:
AUSPERL vermiculite offers an ideal environment for seed germination, supporting both large and small seeds in pure vermiculite or a mix with peat or perlite. It can also be used as a soil improver, enhancing seed emergence and minimizing the risk of capping.

Sowing Composts and Seedling Wedge Mix:
When added to sowing composts, AUSPERL vermiculite improves seed growth and germination. It can be mixed with up to 20% fine peat or blocking compost for use in wedge-shaped plug module systems.

Blocking and Root Cuttings:
AUSPERL vermiculite promotes better aeration, drainage, and insulation in growing blocks, and it can be used in a 50/50 mix with peat or perlite for soft cuttings.

Micro Propagation and Twin Scaling Bulbs:
AUSPERL vermiculite is suitable for weaning tissue-cultured plants and can be used as a rooting medium for propagules. Its moisture-retaining and insulating properties make it ideal for twin-scaling bulb propagation.

Potting Mixes:
AUSPERL vermiculite can be added to potting composts to create a light, open compost that holds more water and facilitates re-wetting. It can be used in various mixes for greenhouse pot plants, hanging baskets, bedding plants, and house plants.
